SPIKE OR NAIL EXTRACTOR.

SPECIFICATION forming part of Letters Patent No. 616,618, dated December27, 1898.

Application filed August 19, 1898i Serial No. 689,003. (No model.)

To @ZZ whom, t 771/607/ concern,.-

Beit known that we, .IoAcHinIvERsox and ADAM REH, citizens of the UnitedStates, residing at IVest Superior, in the county of Douglas and Stateof Wisconsin, have invented certain new and useful Improvements in SpikeorNailExtractors; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improved spike or nail extractor.

It has for its object, among other things, to promote effectiveness andto extract the nailv or spike with a continuous pull and with facilityand expedition.

It consists principally of a grapple composed of suitably-pivoted jawsor claws arranged in a carrier, preferably lateral plates, a wedge alsoarranged in said carrier and adapted to act upon the arms or rear endter minals of said j aws or claws, said wedge having pivotal or movableguides playing in slots in said lateral plates or carrier, a tilting orrocking foot7 or standard, and a lever fulcrumed in said foot orstandard and angularly connected to said wedge.

lVhile as to some details of construction the invention may be variedwithout departure from the spirit thereof, its scope will in general becompassed by the present description and accompanying drawings.

In the drawings, Figure l is a side elevation of the invention in itsinitial position. Fig. 2 is a similar view thereof, showing it as thoughin operation grasping and extracting a spike or nail. Fig. 3 is adetailed view disclosing more fully the grapple.

In carryin-g out our invention we provide a grapple A, composed ofopposite j aws or claws a a, adapted to take under the head or iiange ofa spike or nail at their engaging ends and arranged in a carrier,preferably two lateral plates d, held together at their upper corners bysuitable bolts or pins d2, and having the bolts or pins of, connectingthem together at their lower corners, serving as pivots for said jaws orclaws. These jaws or claws are provided, respectively, just above theirpivots with inwardly-extending projections or lugs a4, projecting pastor by one another, the

function or purpose of which willappear hereinafter. The upper endterminals or arms of the jaws a are recurved, as at d5, to engage orreceive the intermediary portions of the bolts or pins a2 of the platesor carrier a to limit the engaging or lower ends of the jaws to theminimum distance of separation.

B is a wedge also arranged in the carrier, between the lateral plates aa', and adapted to engage the arms of the jaws or claws a, its inclinedfaces being presented toward said arms upon their inner sides, as shown,so, as is apparent, they will spread said arms as the wedge is lifted ormoved upward and cause the lower engaging ends or edges of the jaws toapproach each other, and consequently ef fect the clasping or clampingof an interposed article-as, for instance, the head of a spike ornail-below its flange.

The base of the wedge will engage the interpassing projections or lugsa4 when the wedge is lowered or it is desired to release the hold of thejaws upon the gripped article or spike, the engaging edges or ends ofthe jaws thus being automatically spread or forced apart. v

The wedge B is guided and to a certain extent limited in its movement inthe carrier d by means of guides b, one pivoted to each side of saidwedge and fitted or moving in elongated slots Z2 in the lateral platesof said car= rier.

O is a ha nd-lever, and D is a rocking or tilt ing foot or standard uponwhich said lever is suitably pivoted or fulcrumed, said lever having itsshort angularly arranged arm c adapted to receive and pivoted to theupper end of an extension of the wedge B, whereby it will be seen thatthe grapple in the act of withdrawing or extracting the spike or nailwill be permitted to exert its pull or force thereon in a perpendicularor vertical direc tion while the lever is describing an arcuate movementas required for convenience and facility in actuating the same, as isobvious. Furthermore, by reason of this arrangement and articulation ofparts the grapple, after having exerted the initial pull upon the nailor spike, is adapted to be brought without taking a new bite upon thenail or spike toward the foot or standard, and the extract ing operationthus eifected continuously, said IOO operation being completed byrocking or tilting said foot or standard.

To permit the foot or standard D to have the required tilting or rockingmovement, as aforesaid, it is provided with an upwardcurved runner-likebase d, and to allow the carrier a or its lateral plates to hear againstsaid standard as the grapple, with the spike or nail being extracted, ispulled or moved toward the standard the latter is suitably inclined,asat @,alon g the front edge of its lateral portions, as will be readilyappreciated and as disclosed in Fig. 2.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

l. In a spike or nail extractor a grapple comprising the lateral plates,the jaws pivoted therebetween,projectionsextendinginwardly above thepivots of the jaws and in the path of the wedge, upwardly-extending freearms,y

a wedge itself adapted to force said arms apart and to press saidprojections downward to alternately, and positively, close and openY thejaws, respectively, and guides for said wedge, substantially asdescribed.

2. The combination of the grapple comprising the carrier or lateralplates provided with elongated slots, the jaws or claws pivoted betweensaid plates and having inward-extending projections, and the wedgeadapted to actuate said jaws or claws and to bear upon said projectionsand having pivoted guides moving in said slots of said lateral plates,the standard or foot, and the hand-lever fulcrumed upon said standardand having an angularly-arranged arm connected to said wedge or anextension thereof, substantially as set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
